I just sold my G15 to Saint, I got tired to hell about the click noises. The keys on the G15 are standard height, and it doesn't have a smooth stop for when you click the keys, thus it "clicks". I haven't used it for a year, because I bought a Logitech DiNovo Edge (
http://www.logitech.com/index.cfm/keybo ... 2&cl=gb,en ). The DiNovo Edge has some plusses and some minusses over the G15.
Plusses:
The keys on the DiNovo are VERY smooth. They hardly "click"
The DiNovo Edge uses PerfectStrike(TM)
DiNovo is wireless (Normally, this is a minus for gaming, but the connection between the keyboard and the Bluetooth reciever is sublime, and within 10 meters, there is no delay on the signal.)
The DiNovo has a touchpad built in (At first, I found this useless, but now I am using the keyboard as a remote control for my computer, and it is actually pretty handy.
The Design on the DiNovo far exceeds the one of any other keyboard.
The battery in the DiNovo is also state of the art. 2 hours of charging, and you can run for two months, before you need to recharge.
The DiNovo is a very handy keyboard.
Minusses:
The keyboard has no numpad
The keyboard has no "G" buttons (It has programmable buttons, and it even has a "Fn" key, which in conjunction with another key can be programmed for shortcuts)
It doesn't have an LCD display
It has no "background" light for the keys.
With that being said, I never actually used the G-buttons or the LCD display on the keyboard. I do, however, miss the backlight on the buttons.
Also, the G15 is so damn big and unhandy
Take a normal keybaord, and add around 30-50% to it's length and width, and you have a G15.
